Death or the gladioli!
Most polls show that UI support is around 25 to 30% so I think your a bit optimistic with your % of support and time line.
It's a very crude measurement to use religious background as a measure for support for UK or UI
A Protestant isn't necessarily a unionist and a Catholic isn't necessarily a nationalist/Republican.
I know a number of Catholics that wouldn't vote for an United Ireland & I know a protestant who would vote for whatever he feels would suit his pocket, he has no ideology preference.
When you look at the breakdown of the assembly neither nationalist or unionists have the majority however alliance which is 'neutral' generally get the majority of their support from unionists with a small u.
Demographics have changed a lot in the religious breakdown, this is due to higher death rates to protestants due to having more older people, higher birthrate of catholics and also the majority of foreign born people coming to northern ireland are from a Catholic background as well.
This is basically what SF are hanging their hat on, but as said previously it's not as simple as that.
I'm not saying their won't be an UI in the future but imo it'll be at the earliest around 20 years time but could take 50.
What has this got to do with RAWK?
